NXP恩智浦发布i.MX8M Nano处理器

去年NXP（恩智浦半导体）发布了i.MX8M Mini处理器，非常适合于中高端产品的需求。近期NXP再次发布i.MX8M Nano处理器，这是针对i.MX8M Mini引脚兼容的产品。

i.MX8M Nano对小核进行了升级，由M4升级为M7。但依然是低功耗产品，TDP可以达顾到2W。

• 处理器 – 1到4个 Arm Cortex-A53核心，每个核可达1.5 GHz；32KB L1-I Cache/ 32 KB L1-D Cache; 512 KB L2 Cache
• 实时处理器 – 高达600Mhz的Arm Cortex-M7; 16 KB L1-I Cache/ 16 KB L2-D Cache
  
• Memory I/F – 16-bit DDR3L, DDR4, LPDDR4
• Storage I/F – 8-bit managed NAND with 62-bit ECC, 16/32-bit NOR, QuadSPI
• GPU – 2D GPU, 3D GPU (2x shader, OpenGL ES 2.0/3.0/3.1, OpenCL 1.2, Vulkan)
• Display – 1x 4-lane MIPI DSI with PHY
  
• Audio – 5x SAI (10Tx + 10Rx external I2S lanes), 8-ch PDM input, S/PDIF Tx & Rx
• Camera – 1x 4-lane MIPI CSI with PHY
• USB – 1x USB 2.0 OTG controller with integrated PHY
• Networking – 1x Gigabit Ethernet (MAC) with AVB and IEEE 1588, Energy Efficient Ethernet (EEE) for low power
• Other I/Os – 4x UART, 4x I2C, 3x SPI, etc..
• • Package – FCBGA, 14×14 0.5mm pitch
  • Temperature Range – Consumer: 0°C to 95°C Tj; industrial: -40°C to 105°C Tj
  • Process – 14nm LPC FinFET

软件方面i常规支持Linux 和 Android系统，同时还支持 FreeRTOS 运行在 Cortex-M7 核心。由于 NXP i.MX 8M Nano的l软件是兼容其它i.MX 8M 处理器，所以升级切换也减少了平台差异性。
